Cervical Fascia Flashcards
which layer splits into superficial and deep around trapezius and SCM (4 corners)?
investing
which layer creates suprasternal space?
investing
which layer blends w/ endothoracic fascia peripherally?
prevertebral
which layer blends anteriorly w/ investing and pretracheal and posteriorly w/ prevertebral?
carotid sheath
which layer has two layers that blend w/ superficial cervical fascia in midline?
infrahyoid
which layer has a thickening that becomes stylomandibular ligament?
investing
which layer blends w/ fibrous pericardium?
pretracheal
which layer is continuous w/ nuchal ligament?
investing
which layer embeds cervical parts of sympathetic trunk?
prevertebral
which layer forms a fascial tube from the cranial base to the root of neck?
carotid sheath
which layer blends laterally w/ carotid sheaths?
pretracheal
which layer splits to enclose the submandibular and parotid glands?
investing
which layer is continuous w/ buccopharyngeal fascia?
pretracheal
which layers communicate w/ the mediastinum inferiorly and the cranial cavity superiorly? (clinically important why?)
carotid sheath + pretracheal - infection can spread
what is the largest, most important interfascial neck space?
retropharyngeal space
which layer encloses the sternohyoid and omohyoid?
superficial layer of infrahyoid
what is subdivided by alar fascia?
retropharyngeal space
which layer encloses inferior ends of anterior jugular veins and jugular venous arch?
investing
what does the carotid sheath contain?
- common and internal carotids
- IJV
- vagus
- deep cervical lymph nodes
- carotid sinus n/peri-arterial sympathetic plexus
what permits movement of pharynx, esophagus, larynx and trachea during swallowing?
retropharyngeal space
which layer encloses the sternohyoid and thyrohyoid?
deep layer of infrahyoid
which layer attaches to clavicle, forming pulley for tendon of omohyoid?
superficial layer of infrahyoid
which layer forms a thickening above the hyoid called the intermediate tendon of the digastric?
pretracheal
which layer forms a sheath around the vertebral column, longus colli, longus capitis, scalenes, and deep cervical muscles?
prevertebral
what is closed superiorly by the cranial base and on the sides by the carotid sheaths?
retropharyngeal space
what opens inferiorly into the superior mediastinum?
retropharyngeal space
what fuses w/ fascia on SCM?
superficial layer of infrahyoid
what tethers 2 bellies of omohyoid, changing muscle course?
pretracheal
which layer has lateral extensions that become the axillary sheaths?
prevertebral
which layer merges w/ the superficial layer behind the sternum and onto the pericardium?
deep layer of infrahyoid
what does the deep layer of carotid sheath fuse with?
carotid sheath
which layer fuses with the anterior longitudinal ligament centrally?
prevertebral
